The US servers will come down on Monday, November 26, 2012, at 7:00am PST for a hotfix. The EU servers will come down on Tuesday, November 27, 2012, at 5:00am London Time. The estimated downtime for both US and EU servers is one hour. Patch notes are available after the jump. 

UPDATE:  The updates and bug fixes for the Heroes' Festival will be included in this downtime.  According to Nathan "Kaitheel" McCall this includes:

• A Dream Adventure - Thumore D'Armer's name is now spelled correctly.
• Cloak of the Dream Traveler is now marked "Appearance Only".
• Heroes' Festival is now spelled correctly on the lights and streamer house items.
• Aggressive Advertising in... - no longer allows you to pass out the flyers to mercenaries.
• Gloves are now available for purchase from the Heroes' Festival merchant.
• Festive Flames in Freeport - The Ro Candle location descriptions have been updated to better reflect the locations.

GENERAL

• Fixed a bug where items that dropped from epic monsters that were pre-adorned were not tradable when they should be.
• Spellscrolls will now be more accurate when saying whether or not they’re locked based on spell tier and account subscription level.
• Auto-following while on a flying mount will now cancel your flight if the follow target enters combat.
• Call of the Veteran is now treasured instead of fabled so that all account levels can properly use it.

ABILITIES

• Spells that rely on increments on a target will now successfully check against your implied target if your target is in the same group/raid as you.

QUESTS

• The visage of fear in Vanishing Act should no longer become stuck in an unkillable state.
